Abstract


CdS-CdCO$_3$ thin films were grown by chemical bath deposition.
Different constant deposition temperatures were employed in the
range of 20-80$^{\circ}$C. From X-ray Diffraction (XRD) results can be
observed that intensity of CdS peak is abruptly reduced when
deposition temperature is decreased. By SEM images the formation and
change in shape and size of crystallites can be observed as
temperature is decreased. The forbidden energy band gap was 2.4-4.1
eV, determined from optical absorption. The formation of products
was further confirmed with FTIR studies.
